Description

[Detailed description of the invention]

(a) Industrial Application Field The present invention relates to a bubble-generating bathtub that can be used to clean a filter. (B) Conventional technology Conventionally, as disclosed in Japanese Patent Laid-Open No. 59-135058, the bubble-generating bath 10 has a bathtub with hot water between the bathtub body and a circulation pump installed outside the bathtub body. Generally, a circulation flow path is provided, and an air intake part is provided in the middle of the bath water circulation flow path, so that when the circulation pump is activated, the bath water mixed with air bubbles is ejected into the bathtub body. . In the bubble-generating bathtub described above, a separate bypass flow path is formed in the middle of the bath water circulation flow path in which a filter is interposed for filtering a part of the circulating bath water, and the bypass flow path has three directions. There is one in which a valve is placed upstream of the filter and a drainage channel is communicated with one end of the three-way valve. In such a bubble generating bath, when cleaning the filter,
By switching the three-way valve, the bypass flow path that communicates with the upstream side of the bath water circulation flow path is communicated with the drainage flow path, and a portion of the circulating bath water is passed into the bypass flow path from the downstream side through the filter and then passed upstream. By causing the water to flow backwards toward the side, the filter can be washed and the washing wastewater can be discharged from the drainage channel. (c) Problems to be Solved by the Invention However, in the case of the above-mentioned bubble-generating bathtub, even during the cleaning operation of the filter, the end of the bath water forced flow path remains open and communicates with the bathtub body. In order to efficiently clean the filter, when the rotation speed of the circulation pump is set to the maximum, a strong jet is emitted inside the bathtub, causing children and the elderly to get tripped up and fall. There was a risk of such. In addition, users often do not take a bath while cleaning the filter, and the fact that hot water is squirted into the bathtub itself is unpleasant for the user. For this purpose, it is possible to install a valve in the middle of the bath water forced flow path to prevent the bath water from gushing into the bathtub body during the filter cleaning operation, but due to problems such as maintenance of such valves, it is difficult to solve the problem. Therefore, it was difficult to implement. (d) Means for Solving the Problem Therefore, in the present invention, a bathtub consisting of a bath water suction channel and a bath water forced flow channel is provided between the bathtub body and a circulation pump installed outside the bathtub body. A hot water circulation flow path is provided, a jet nozzle is provided at the discharge portion of the forced bath water flow path into the bathtub body, and an air intake portion is connected in communication with the bath water filling flow path. In a bubble-generating bathtub configured to be able to spray bubble-mixed bath water into the bathtub body, a bypass flow path is provided in the middle of the bath water circulation flow path with a filter for filtering a part of the circulating bath water. It is possible to wash the filter by making a part of the circulating bath water flow back into the bypass flow path, and the spout of the spout nozzle can be opened and closed, so that the spout nozzle is closed during filtration cleaning. It is an object of the present invention to provide a bubble-generating bathtub that is configured to stop the spouting of bath water and is capable of cleaning a filter. Another feature is that the opening/closing amount of the spout nozzle can be adjusted, and the spouting of bath water from the spout nozzle is stopped or the spouting amount is minimized during filtration cleaning. (e) Actions and Effects According to the present invention, the following effects are produced. ■During the cleaning operation of the filter, the spout nozzle can be closed or slightly opened to stop the spout of hot water into the bathtub body or to reduce the amount of hot water spouted into the bathtub body. The backflow of bath water becomes larger, and the cleaning efficiency of the filter can be improved. ■Even if the rotation speed of the circulation pump is set to the maximum in order to improve the cleaning effect, there is almost no spouting of bath water from the spout nozzle, so there is no risk to children or the elderly taking a bath, and the filter can be cleaned. It is possible to increase efficiency and ensure the safety of bathers. ■While the filter is being cleaned, bath water can be prevented from spewing out into the bathtub body, so users who are not taking a bath during that time will not be uncomfortable.

. Among them, Wave Blow C is the circulation pump (P) rotation.
The rotation speed changes in a nearly catenary curve, near high rotation speed.
The rotation speed increase rate and rotation speed decrease rate are large at low rotation speeds.
Because the rotation speed increase rate and rotation speed decrease rate near the number are small,
, strong changes in the jet flow occur in a relatively short time, and weak changes in the jet flow occur in a relatively short time.
The effect is sharp and occurs over a relatively long period of time, and the bather

The timer operation starts and the number of hours displayed on the timer starts.
The value decreases every second (595). Also, press the timer switch (114) while the timer is running.
Without pressing the button to turn it on (80ON), the timer is turned on.
The timer has elapsed and the timer shows ro: OOJ.
If it reaches (605), the time display is changed to 0.

You can avoid causing discomfort. Margin below c] [IV-5) State transition of strength level in blowing operation
In the operating procedure based on the flowchart of [IV-1]
The strength level is “strong” or “thin” for each jet type.
j Set the level to 5 levels: “medium-weak” and “weak”, and
Considering the content of each jet form, the strength was varied.
Even if the intensity level is displayed as “medium”, the jet form may differ.
In other words, the jet strength is different. The state transitions of such strength levels are shown in Table 4.
That's right. In Table 4, in the vertical direction, the operation stop state and the five levels of strength are shown.
